MR. SOLON:
The angle that we made
was a little over two degrees = two out of 360.
The group of drawings which we have
here lllustrate the kinds -- we utilized a
rather idealized kind of structure for mathe=
Matical simnlicity,.
Our structure first of all was a
oylinder whioh ts unlike, of course, most prroti=e
cal buildings which are rectangular,
We assumed no attenuation by the
roughness of the terrain and we assumed no
collection on the sides of the building.
;
We also assumed for the purposes of
this vreliminary exploration of this problea
that the building wag dustefree and one was not
concerneé with fallout ingsidé the building,
This showa the variation in the reo
lative contributions from the roof and from the
extended plane as a function of two pirdmeters,
nemely the height of the roof, the height measure
ie really the height of the roof plus three feet
and the path width= or the radius of our cylin-
drical building,
As one can see here, the contribution
